Abstract:
Dual-headed, auto-sensing, spray hand washing device, comprising liquid storage bottles (300); a device head (100), the device head comprising a housing (110), a switch (120), sensors (130), and a control circuit board (111), the housing (110) being provided with two water outlets; micro-pumps (112), connected to the control circuit board (111), arranged inside the housing (110), and provided with liquid extraction tubes (113) connected thereto; a liquid outlet channel (140), arranged between the micro-pump (112) and the water outlet; and an atomizer nozzle (200), arranged at the outlet end of a liquid outlet channel (140), there being one or more atomizer nozzles (200) provided, and the nozzle comprising a water outlet chamber (211) and a water outlet piece (210), a water outlet hole (212) being provided in the bottom of the water outlet chamber (211). A plurality of cyclone slots are provided (230), arranged at the bottom of the water outlet chamber (211), extending from the water outlet hole (212) to side walls of the water outlet piece (210), and surrounding the water outlet hole (212) in a clockwise or counterclockwise distribution; and a gap is reserved between a blocking piece (220) and the water outlet hole (211). An outwardly scattering spray is naturally formed by means of the atomizer nozzle (200), without requiring the provision of a geared transmission, and thus the invention has such strengths as a simple structure, low production costs, and convenient assembly, while also being advantageous in terms of volume, cost, and production efficiency.
